All the gas comes from the same pipeline. All the tank-trucks pull from the same refineries. As stated earlier, the difference is the additive. What’s more important is which retailer you buy from i.e. the age of the retailer. Newer ones will have new equipment, filters, pumps, underground tanks made of fiberglass, etc. Old ones can have old steel tanks, corrosion, no filters, etc. Put a can of additive every few thousands of miles and you’ll be fine. And don’t fall into the ‘high-octane’ myth. New cars’ computers will automatically adjust to lower octane settings and your car will be fine. Also, I wouldn’t have believed it unless I saw it with my own eyes, but certain markets have oil packagers/blenders (whom the oil companies hire to bottle/package oil on their behalf) and it is often the EXACT same oil going into the different bottles. No additive difference or anything like that... once saw twelve different branded bottles (Castroll, Pennzoil, BP, Havoline, etc) with the exact same petroleum 10w-30 being dispensed into different branded bottles during a tour of a packager. Really fascinating what role marketing can play!

In my experience as someone who has drag raced his whole life, I've found it(octane) does make a difference with performance. It just runs better with higher octane in it, and I want every bit of power underneath my foot if I need it. It is still possible to ruin an engine even with knock sensors etc. I've done it. Burned a hole in 2 pistons. Granted that was a stock turbo car turned into a race car. Got to the point where when racing, I had to run race gas for the high boost I was running. I know this is an extreme situation, but it makes a difference. If it is a high performance car, I'm going to run what the manufacturer says; but that's just me. Economy car I'll run low grade. My mom runs low grade in her turbo BMW and it just kills the power it's supposed to have. To each there own. I want every horse.
My Porsche 911 Turbo has a tune that requires 100 octane in a certain setting. Our LS cars don’t need it. Naturally, running it doesn’t hurt a thing, just costs more money. There’s a video floating around online somewhere about a test done with a bunch of 911’s that showed no measurable difference using all flavors of gasoline on a 911 turbo...made no difference. I actually use 86 octane with my 911 when traveling, but NOT with the performance setting...only 100 octane then.

IMO, there are some out there who thinks ECU has an indefinite ability to compensate timing for knocking of the engine. I think this is dead wrong idea. It is beyond me using regular gas after buying a car designed to run with higher Octane gas for optimum design specs.

It can, but it has its limits. I agree with you. I will run the octane that is suggested. This is a premium vehicle and I'll give it the best. There is a reason for the suggestion.

Here’s a good article you guys will like (the author use 91 octane fuel). In the USA, our cars run fine on 87, 89 and 91 octane fuels. In LA, we have 93 octane as our ‘premium.’ If someone wants to use that fuel, be my guest. The benefits you see will be irrelevant (maybe make you feel warm and fuzzy, but can’t be measured in any significant way) and you’ll simply spend more money at the pump. You wouldn’t even know if you were dumping in 87 octane fuel from a tank that was supposed to distribute 91 octane...the oil jobbers make mistakes about that all the time and deposit the wrong gasoline in the wrong tank. We also have ‘ethanol free’ fuel here in LA and you can pay 30% more for it if you want. (We all know ethanol wreaks havoc on fuel systems when sitting for long periods of time).

I thought we had beat this horse to death in earlier post. As I recall we had generally come to the conclusion that "If you can't run with the Big Dogs stay on the Porch" on this issue. If you can't afford to put 93 Octane in your LS and you can justify running 87 Octane in your own mine by claiming that 87 Octane is just as good then fine go with 87 Octane. But as far as me and my LS we will always run the best 91/93 Octane. Oh and I don't run High Tech 0W-20 oil from Walmart in my LS either.

The point is everyone takes care of their LS in their own manner. We can all read and we all understand what Lexus means when it says you should run premium fuel in the LS and we all know it's not 87 Octane. And to say that High Tech oil is the same as Amsoil is just not true. My point was that some folks just don't want to spend the money to take care of their LS as others see it should be, it may be that they don't have the money or it may be that they just don't want to spend the money. It doesn't matter but stop the insane debate about which is better. 91/93 vs 87 is like Chevy VS Ford

So Noted. For the record I don't use Amsoil either. I use Toyota 5W20
